Architecture of Istanbul
Architecture of ancient Rome, Byzantine architecture, and Ottoman architecture
Istanbul is primarily known for its Byzantine and Ottoman architecture, but its buildings reflect the various peoples and empires that have ruled its predecessors. Genoese, Roman, and even Greek forms of architecture remain visible in Istanbul alongside their Ottoman counterparts. Similarly, while the Hagia Sophia and imperial mosques dominate much of the city's skyline,
the city is also home to a number of historic churches and synagogues.
More than two thousand years following the departure of the Greeks, few examples of Istanbul's Greek architecture have survived. Perhaps the most prominent relic of the Greek era is Maiden's (Leander's) Tower. Residing on an islet in the Bosphorus just off the coast of Üsküdar, Maiden's Tower was first built by the Greeks in 411 BC to guide ships within the strait. Since then, however, the tower has undergone a number of enlargements and restorations, rendering its connection to the Greeks tenuous, and today merely serves as an observation point Examples of Roman architecture have proved themselves to be more durable. Obelisks from the Hippodrome of Constantinople, modeled after the Circus Maximus in Rome, are still visible in Sultanahmet Square
